[Python-modules-team] Bug#836851: python-django-registration-doc: fails to upgrade from 'jessie' - trying to overwrite /usr/share/doc-base/django-registration-overview

[Andreas Beckmann]

Package: python-django-registration-doc
Version: 2.1.2-2
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts

Hi,

during a test with piuparts I noticed your package fails to upgrade from
'jessie'.
It installed fine in 'jessie', then the upgrade to 'stretch' fails
because it tries to overwrite other packages files without declaring a
Breaks+Replaces relation.

See policy 7.6 at
https://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces

>From the attached log (scroll to the bottom...):

  Selecting previously unselected package python-django-registration-doc.
  Preparing to unpack .../python-django-registration-doc_2.1.2-2_all.deb ...
  Unpacking python-django-registration-doc (2.1.2-2) ...
  dpkg: error processing archive /var/cache/apt/archives/python-django-registration-doc_2.1.2-2_all.deb (--unpack):
   trying to overwrite '/usr/share/doc-base/django-registration-overview', which is also in package python-django-registration 1.0+dfsg-2
  Errors were encountered while processing:
   /var/cache/apt/archives/python-django-registration-doc_2.1.2-2_all.deb


cheers,

Andreas
